When I started quilting, I made larger to extra large king quilts. When all our beds overflowed, DD didn't want anymore, lg space for lg wall hanging filled up, swiched to couch quilts. Then made art quilts. About this time I've had major injury to both shoulder with surgery. And discovered I don't like repitition. So the size has gotten smaller. Also, with art quilts that take a lot of thinking and design time, my quilts have gotten even smaller, some the size of a standard piece of copy paper. Now I'm working on comfort quilts from preme to large couch quilt (depends on the amount of fabric in stash). I'm trying to make larger art quilts with more story.
So to each his own and in his season.
